BUG/MINOR: tests: fix namespace getter logic

[ehpc]

You need brackets here if (r < 'a' || r > 'z') && r != '-' because bool || bool && bool == bool || (bool && bool) and as such we are basically ignoring r != '-'.

Proof:

func main() {
	r := '-'
	if r < 'a' || r > 'z' && r != '-' {
		fmt.Println("SHOULD NOT RUN")
	}
}
